De acordo com o resumo o presente trabalho visa coletar informações atualmente existentes com referência aos fatores que influem na resistência ao calor. Tanto os fatores intrinsecos são comentados para poder fornecer a completa cobertura do assunto.
A influência desses fatores sobre os esporos e as células vegetativas das bactérias são discutidas paralelamente para efeito comparativo e também para mostrar as discrespâncías comumente empregados na literatura.

O trabalho visa estudar o efeito da contaminação com bactérias láticas leuconostoc sp e Laetobacillus sp isoladas de dornas de fermentação das usinas de álcool sobre a fermentação alcóolica por leveduras.

"A fast method for identification and enumeration of E. Coli in whole liquid egg and egg white usinmg membrane filter (MF) techinique was developed. Sample were treated with bacterial protease (Alcalase)( and filtered through membrane filter 0.45 [um] pore size microbial cell retention. For sample of whole liquid egg, treatments with sodium hidroxide and tween 80 were carried out prior to the 18 h. incubation at 35 (graus centígrados) on m-Endo agar. This tecnique results indicated tahat MF techinique was suitable for enumeration and identification of E. coli in egg white ata a concentration as low as one cell per gram of sample. With whole liquid egg, the results must be corrected by a factor 2.6."

Chicken microbial loads, estimated through absorbance increase of culture medium inoculated with the contaiminant microflora of the carcasses, were compared with total plate counts and psychotrophic counts obtained on the same carcasses, using the pour plate method after 0,48, 96 and 144 h stored chicken at 4 to 5 C.
For estimating microbial loads on the carcasses, the mathematical relation 1n AO = 1n A1 - R - Kt was used, which was developed by combining the growth and R equations (described in Materials and Methods) and using data at 28 C. The values obtained by this method, when compared with those of plating, give correlation coefficients of 94, 91, 88, and 64 for total plate counts after 0, 48, 96, and 144 h. of storage and 94, 83, 82 and 86 for psychrotrophics counts after 0, 48, 96 and 144 h. of cold storage. The method proposed in the present work permits the estimation of psychrotrophics and total counts in no more than 11hr. wich is very primising for industrial...
